In short
Chatbase lets you build, on your own, an AI agent fed with your content, with plans based on a number of message credits. KernChat is an assistant prepared with you, with handover to your team, contact memory and AI usage included in a fixed subscription.

Chatbase made it simple to build an AI agent on your own content: you provide your pages or documents, set up the agent and publish it, all self-service, with a 7-day trial to get a feel for it. To test the idea of an assistant on your website without committing, it is a good starting point.
The two offers side by side
| Criterion | KernChat | Chatbase |
|---|---|---|
| Starting price | Subscription from €100 excl. VAT a month, set-up from €1 500 excl. VAT | Hobby: $40 a month for 700 message credits ($32 billed yearly), 7-day trial |
| Billing unit | One subscription per level, no credits | Message credits: 4,000 for $150 (Basic), 15,000 for $500 (Business) a month |
| Set-up | Done with you, after a one-hour audit | Self-service |
| Around the assistant | Handover to your team, contact memory, suggestions, links to your tools | One AI agent on your content per plan, $25 a month per extra agent |
What KernChat does differently
- A team behind the assistant. When it does not know, the conversation goes to someone on your team in a shared inbox
- Reviewed knowledge. Your documents are prepared with you, and unanswered questions become suggestions to approve
- Contacts with a memory. With their consent, the assistant remembers what they said, for a period you set
- No credits. AI usage is included: a busier month does not eat into a stock of messages
Example bill for an SME
An SME receiving a few hundred questions a month will often choose Basic: $150 a month for 4,000 message credits, one agent and 3 seats, at the prices listed on 30/10/2026, or $120 a month billed yearly (20% less). Chatbase's page explains how credits are consumed. This calculation is an example, excl. VAT.
KernChat has no credits: AI usage is included in the subscription, within the conversation volume of your level.
KernChat's limitations compared with Chatbase
- No self-service trial. Chatbase lets you test it on your own for 7 days, straight away; KernChat starts with an audit
- A paid set-up. It includes document preparation and testing, but it is an upfront cost
- One assistant per need, built with you. Chatbase lets you add agents yourself, at $25 a month each
Questions to ask before choosing
- Do you want to test an idea on your own, or launch an assistant that represents your business?
- Who takes over the conversation when the AI does not know?
- Does the assistant need to remember your customers and pass requests to your tools?
- Who checks what the assistant says each month?
In summary
Chatbase is the right tool to try an AI agent on your content quickly and on your own. KernChat fits when the assistant becomes a real workstation: connected to your team, your contacts and your tools, and followed up every month.
